At the 2025 LED Display Industry Development Focus Forum held in Shenzhen, one message came through clearly: COB is no longer just a “cutting-edge option”—it’s becoming one of the core engines pushing the LED display industry forward.

As COB scales, the competition is getting tougher, the pricing is dropping faster, and the application map is expanding beyond “high-end pro rooms” into everyday commercial spaces—especially where glass + transparency matter.

If you’re evaluating transparent display routes in 2025, start with the broader decision framework in the Transparent LED Display Guide.

COB Technology: From “Pioneer” to Mainstream

What is COB (and why it’s different from SMD)?

COB (Chip-on-Board) is a packaging route that mounts LED chips directly onto a PCB substrate. Compared with traditional SMD, COB removes the “independent package” step—LED chips connect more directly to the board-level system.

What changes on the screen (real-world value)

Forum discussions highlighted several practical upgrades COB brings:

• Ultra-fine pitch becomes easier to industrialize, with pitch targets like P0.9 and even P0.7 being more achievable.
• The classic SMD “caterpillar” look (visible discrete lamp structure) is greatly reduced, so the image appears cleaner and more refined at short viewing distances.
• Reliability improves because COB’s fully enclosed module structure better protects LED crystals and electrical connections from water vapor, heat, vibration, impacts, and other disturbances.

One widely repeated claim at the forum: annual maintenance cost for COB can be as low as ~43% of comparable SMD products (application and environment dependent).

For teams who care about “why some factories can deliver stable COB and others can’t,” see our process and QC viewpoint on Technology & Quality.

Market Expansion: Growth, Capacity, and Faster Price Drops

Forum data pointed to a rapid scale-up:

Market size is accelerating

TrendForce (集邦咨询) estimates global COB output value could reach ~USD 815M this year, +25% YoY, outpacing the broader LED display market growth rate.

Capacity is expanding (including LCD panel makers entering)

COB capacity was cited around 60,000㎡/month in 2024, projected to reach 88,700㎡/month this year, with ~20,000–30,000㎡/month of added capacity.

A major driver is the entry of traditional display giants and panel-related manufacturing ecosystems, reshaping the competitive landscape.

Price decline is now a key adoption engine

In Q1 2025, the average COB product price reportedly dropped ~31.4% YoY—a larger decline than SMD—making COB economically possible in more scenarios.

Applications: From Professional Rooms to Everyday Commercial Spaces

As cost drops and reliability rises, COB is expanding quickly:

Core professional applications still lead

COB remains strongest where stability and image quality are non-negotiable:

• command & control centers
• premium meeting rooms
• high-end commercial display and showroom environments

Emerging scenarios are scaling up fast

Demand growth was emphasized in:

• virtual production
• smart education, including large single projects over 500㎡
• cinema LED deployments, with new installations projected to rise sharply (the forum cited ~140 new screens globally this year, +75% YoY)

The notable shift: COB starts entering “transparent commercial display”

A particularly important trend: COB is pushing into more diverse spaces—storefront windows, chain restaurants, museums, financial institutions, auto dealerships, exhibitions—where transparent COB can reshape how “glass” behaves as a media surface.

This is where ChinaLEDScreens positions itself differently: transparent LED is our long-term lane, not a side project. Explore our portfolio at ChinaLEDScreens.

ChinaLEDScreens’ Innovation Path: Transparent COB + Dual Product Lines

1) Transparent COB “crystal-core” screen concept

ChinaLEDScreens’ differentiated COB direction centers on transparent display engineering:

• LED bare-die “ball planting” process approach (as described)
• transparent film-based lamp board materials
• etched transparent mesh circuitry on the surface

The intended outcome:

• when powered off: close to ordinary glass
• when powered on: saturated, dynamic visuals
• transparency claim: up to ~95%

For a product-direction reference aligned with this route, see our Transparent Flexible LED Film Screen (COB).

2) Dual-line matrix: transparent + holographic “invisible” display

ChinaLEDScreens also described a second product line: a holographic / “invisible” screen concept designed to reduce the boundary between display hardware and architecture:

• no-keel style fixing concept
• thickness claim: under 2mm
• transparency claim: 80%+

If you’re designing experience-driven retail or stage visuals, see Holographic LED Screen.

3) Cost-performance as a competitive lever (not just “premium specs”)

A central point in the forum narrative: transparent products must be commercially practical.

ChinaLEDScreens claims:

• max power: ~200W/㎡
• average power: ~30–50W/㎡
• energy savings: 70%+ vs conventional products (as stated)

That kind of operating-cost reduction matters most to:

• chain retail groups
• integrators managing multiple sites
• property owners scaling media façades and glass signage

Future Outlook: Big Opportunity, Real Challenges

Overcapacity risk is emerging

With yield assumed at ~90%, the forum cited actual capacity utilization only ~60–65%, suggesting oversupply pressure is already showing.

Meanwhile, the number of companies with ≥200㎡/month capacity reportedly rose from 7 (July 2023) to 16 (2025)—reducing market concentration.

Technology route competition continues: COB vs MiP

COB and MiP (Micro LED in Package) are still competing. Some industry players expect coexistence, not a winner-takes-all replacement.

Common breakout directions the industry is exploring

Forum discussions highlighted paths like:

• doubling down on P1.2 as a core battleground
• pushing back into value segments above P1.5
• accelerating overseas expansion
• developing high-protection COB (UV resistance, salt-fog resistance) for harsh outdoor conditions

What This Means for Buyers and Specifiers in 2025

If you’re a display engineer, integrator, architect, or contractor, here’s the practical takeaway:

• COB is becoming easier to justify because pricing is dropping and reliability is improving.
• The fastest growth is not only “meeting rooms”—it’s scenario-based display, including glass + transparency.
• The winning suppliers won’t be the ones with the best brochure specs—they’ll be the ones who can deliver stable production, documentation, QC, supply chain continuity, and after-sales support.
